Thanks for the correction. My code is untested, as you can clearly see. I hope you didn't take my criticisms as flames; publicly-posted code is meant to be scrutinized so that it can be improved. I have more to learn than most people when it comes to improving my code, anyway. :-)

Oh, as far as the tar command only untar/zipping files in the current directory, you can change your current directory to the appropriate subdirectory by using the chdir command.
